Extending the company's nonvolatile Static Random Access Memory (nvSRAM) portfolio, Cypress Semiconductor has announced the 16Mb nvSRAM family. These devices target mission-critical applications including high-end PLCs, high-speed data/error loggers in storage equipment, networking equipment, avionics systems and electronic gaming machines.

Featuring access times as low as 25ns, the devices are claimed to be the fastest high-density asynchronous nonvolatile RAMs on the market. The nvSRAMs are offered with an optional integrated Real-Time Clock to enable time-stamping of critical data to be logged. Suited for applications requiring continuous high-speed reading and writing of data and absolute nonvolatile data security, the nvSRAMs feature infinite read, write and recall cycles, with 20 year data retention at 85˚C and 150 years at 65˚C.

The family comprises devices with asynchronous parallel and asynchronous Open NAND Flash Interface (ONFI) Standard 1.0 interfaces. The ONFI 1.0 devices operate from a 3V power supply, 1.8V I/O supply, in data bus widths of 8- and 16-bit. The asynchronous parallel devices are offered with and without an RTC, in data bus widths of 8-, 16- and 32-bit, and at power supply levels of 3 and 5V with 1.8V I/O supply.

Rainer Hoehler, Senior Director, Nonvolatile Products Business Unit, Cypress Semiconductor, commented: "Mission-critical systems require high-performance memories that can capture data instantly and reliably on power loss. Cypress’s 16Mb nvSRAMs deliver absolute data security with the industry’s fastest high-density NVRAM. The ONFI 1.0 interface option also allows customers using NAND controllers to leverage the unmatched performance of our nvSRAMs."

The ONFI 1.0 devices are available in a 165-ball FBGA package, while the asynchronous parallel devices are available in 44-pin TSOPII, 48-pin TSOPI, 54-pin TSOPII, and 165-ball FBGA packages.
